All of the following are true for pseudopelade of brocq except?
**Core Concept**
Pseudopelade of Brocq is a rare, idiopathic scarring alopecia characterized by progressive loss of hair follicles and replacement with scar tissue, leading to permanent hair loss. This condition is often associated with chronic inflammation and immune-mediated destruction of hair follicles.
**Why the Correct Answer is Right**
The correct answer, **(D) Presence of pustules**, is incorrect because pseudopelade of Brocq is typically characterized by the absence of pustules, inflammation, and other signs of active dermatitis. In contrast, conditions like folliculitis or acne may present with pustules. The presence of pustules would suggest an infectious or inflammatory process rather than the chronic, scarring alopecia seen in pseudopelade of Brocq.
**Why Each Wrong Option is Incorrect**
**Option A:** Scarring Alopecia - This statement is true for pseudopelade of Brocq, as it is a type of scarring alopecia characterized by permanent hair loss and replacement with scar tissue.
**Option B:** Inflammation is absent - This statement is also true for pseudopelade of Brocq, as the condition is often characterized by the absence of active inflammation.
**Option C:** Foot print in snow appearance is seen - This statement is true for pseudopelade of Brocq, as the condition can present with a characteristic "footprint in snow" appearance on biopsy, where the hair follicles are replaced with scar tissue.
**Clinical Pearl / High-Yield Fact**
Pseudopelade of Brocq is often difficult to diagnose clinically, and a biopsy may be necessary to confirm the diagnosis. It's essential to distinguish pseudopelade of Brocq from other scarring alopecias and conditions that may present with similar clinical features.
**β Correct Answer: D. Presence of pustules**
